Vitamin K (Nutritional) Blood Test

£99.00

Vitamin K refers to a group of fat-soluble vitamins that play a role in blood clotting as well as regulating blood calcium levels and bone metabolism. In the liver, vitamin K is required to produce 4 factors that are necessary for blood to properly clot: prothrombin and factors VII, IX, and X.

Most people get all the vitamin K they need by eating a varied and balanced diet. Because vitamin K is a fat-soluble vitamin, any vitamin K in the body that is not needed immediately is stored in the liver for future use. Green leafy vegetables including broccoli and spinach, vegetable oils and fortified cereals are all good sources of vitamin K. 

In the UK for those who eat a healthy, balanced diet a vitamin K deficiency is rare. However, those at risk of developing a vitamin K deficiency include those with conditions that limit absorption of dietary vitamins such as biliary obstruction, coeliac disease, ulcerative colitis and cystic fibrosis. Vitamin K supplements are also available but monitoring the dose is important as too much can be harmful, so it is advised you speak with your doctor before supplementing vitamin K.

This test measures the level of vitamin K in your blood.
Fast 8 - 10 hrs prior to sample being taken. Do not consume alcohol 24 hrs before test or cease prescribed medication without consulting your Doctor. Protect samples from light. Wrap in foil.
